Title: Ticket sales information managing method
Inventor: OSAKI NOBUYUKI
IPC: G06Q30/06
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To transfer a ticket without necessitating a labor and time for becoming a member in advance by using reservation authentication data and transfer authentication data. SOLUTION: When a consumer A desires to transfer a reserved ticket to a consumer B, the consumer A applies for the transfer of the ticket to a transferring ticket application receiving means 104. When the means 104 authenticates the correctness of the reservation based on the reservation number 107 and reservation authentication data 108 of a table 106, the means 104 correlates reservation number 111 and transfers authentication data 112 to store it in the table 110 to delete writing in the table 106. Next, the consumer B informs a transferring ticket reception receiving means 114 of the number 111 and the data 112 reported from the consumer A. After the table 110 authenticated the consumer B to be a right person to be transferred from the number 111 and the data 112, the means 114 correlate the number 107 with the data 108 and register them in the table 106. Thus, the consumer B obtains this reserving right.

Title: Heat collecting apparatus
Inventor: TAJIMA MASAHISA
IPC: F24S90/00
Filed: 1984-08-30
Abstract: PURPOSE:To secure the amount of heat to be collected even when insulation is scarce or the ambient temperature is low, by using a heat pump for the heat collecting operation and collecting heat by using both or one of a solar heat collector and a heat recovering type heat collector. CONSTITUTION:A heat collecting apparatus consists of units including heat collector units comprising a heat accumulating tank unit, a heat exchange unit, a refrigerant distributing unit, a solar heat collector 6, etc. A high-temperature and high-pressure discharged gaseous refrigerant that has been compressed by a compressor 1 flows into a radiator 2 where the heat of the refrigerant is radiated to hot water flowing in a water heater 15 and the refrigerant condenses into a liquid. The high-pressure refrigerant that has liquefied in the radiator 2 is passed via a first electromagnetic valve 3 and a second electromagnetic valve 8 into a heat collector. The heat collecting action of a heat recovering type heat collector 11 is effected in such a way that when the first electromagnetic valve 3 is closed and the second electromagnetic valve 8 is opened, the liquid refrigerant that has been condensed in the radiator 2 passes through the second electromagnetic valve 8 and a second high-pressure connecting pipeline 9 into a second expansion valve 10. When the refrigerant passes the second expansion valve 10, it is reduced in pressure and temperature, and flows into the heat recovering type heat exchanger 11 where it absorbs the heat of the exhaust gas to evaporate, and the resulting gas returns via a second low pressure connecting pipeline 12 to the compressor 1.

Title: Vertical magnetization type magnetic head
Inventor: FURUKAWA TERUO
IPC: G11B5/48
Filed: 1983-09-27
Abstract: PURPOSE:To narrow a guard band between tracks and to increase recording density by arranging two heads having different azimuth angles each other in the width direction of tracks with a minimum distance. CONSTITUTION:The main magnetic poles 1a, 1b have azimuth angles alpha1, alpha2 which are respectively equal to positive and negative angles to the width direction of the tracks 9a, 9b,.... The main magnetic poles 1a, 1b, magnetic exciting cores 4a-4d and magnetic cores 5a-5d are arranged on heads 12, 13 point- symmetrically to the center point of the track width direction of the main magnetic poles 1a, 1b on a plane parallel to a recording medium 7. Consequently, the width of guard bands 10a- can be reduced and the concentrical generation of crosstalk to one position is prevented. Since the tracks 9b, 9c are simultaneously recorded by one united-type head 11, crosstalk in a reproduced signal is reduced by the azimuth effect even if the head 11 is overlapped to the adjacent track 9a.

Anisotropic etching as represented by reactive ion beam etching under a low pressure is used as the etching method. The projecting parts of the substrate 1 are etched and the ruggedness is inverted in the region where the photoresist 2 remains in the recessed parts. On the other hand, the height over the entire part is lowered while the shape of the ruggedness is maintained in the other region where there is no photoresist 2.

Abstract: PURPOSE:To enhance a selective ratio by executing an etching operation by using a gas in which bromine used as a main gas has been mixed with oxygen or steam of less than specific % of the main gas singly or with a combination of these as an additive gas. CONSTITUTION:When silicon is etched by introducing a gas into a reaction chamber and by transforming the gas into a plasma after applying a high frequency, it is etched by using a gas in which bromine used as a main gas has been mixed with oxygen or steam of less than 25% of the main gas singly or with a combination of these as an additive gas. When the oxygen or the steam is added to the bromine in this manner, silicon dioxide is generated as a deposition for sidewall protection use; consequently, a high selective ratio can be obtained with reference to the silicon dioxide of a substratum.
